Application filed september 26, 1925, Serial No. 58,942, and in Great Britain October 22, .1924.

This in'ventionrelates to finishing machines and is illustrated as embodied in an automatic machine for setting the edges of the soles of boots and shoes of the type shown in United States Letters Patent No. 1,078,68l5 granted November 18,-1913, upon" the application of Frank B. Keall, Joseph Gouldbourn and Arthur E. Jerram. V Prior to the operation of setting the edges of the soles of shoes by means of a heated, rapidly vibratingiron a stain is usually applied to the margin ofthe sole, and this stain usually contains a small component of Wax. It has been found'that the action of the vibrating toolctends to produce a slightly undulating effect onthe edge being finished, which in the higher grades of Worl; is objectionable. Apparently this is due to small ridges of Wax which are left on the edge at the ends of the strokes of the iron.

"merry, an object of the invention is to obviate the ditiiculty above mentioned.

This we accomplish by providingan improved machine of thetype referred to hav-' ing mechanisinfor varying the character of the operation of the tool during different traversing movements,

In the illustrated arrangement, in accordance- With a. feature of the invention, the

supply of. power :to the tool is interrupted prior to the-lasttraversing movement-sothat the setting of the shoe is concluded by a mere Wipe of the ron, along theedge with the ry pos tion and not.

stop the iron at a definite point in its pathof vibration.

Wherever poweris supplied to'the vibratingtool'by m ans of a driving'belt, the mere slackeningof the belt may-not be sutlicient' to stop the vibrations of the finishing tool aeca'use of. the small amount of power re-f quired for its oscillation. In view of this,

action e tier-tire. the vibrating;

v A feature o'f the in vention relates to mechanism.arrangedto anotherfeature'of the invention consists in means arranged toliftthedriving belt out. of contact Withthe highest portioniofi' thepulley at the sametime that the tool driving beltis slackened.

In machines of thekind referred to it has been usual to cause the edge setting iron to be moved away from the shoe and to stop the machine in a region along theforepart which is comparatively straight and which therefore renders easy: the movement of the iron into engagement with the edge of the sole on I the next shoe to be operatedupon. The-last traverse of the shoepast the'iron was th'ere{ the iron'is stationaryand is aetingto smooth or sleek the edge of the sole, the iron were removed before the endof the travers'e an undesirable mark, such as ahumpofWaX, Would be left on the edgeof the sole'at the point Whereth'e iron was removed: Another feature of. the. invention therefore relates to mechanism by means of which the iron is maintained incontact with the 'edge of the sole until the end of the traverse at the shank is reached. 'lhe i'llustrated machine provides 7 mechanism associated \vith the mechanism;

forfreversingthe traverse of the shoe Which in this type of machine at a comparatively 'sirability ofapplying the .tool to the 'a vork straight portion of-the forepart of the shoe,

still another feature of the invention relates to mechanism arranged-to cause. a partial traversing movementsubsequent to "the re moval of the iron from the Worlcso that. a comparatively straight part of the forepart of the shoe is positioned opposite the iron. when the machine stops. f In the-illustrated machine the release of the tool-controlling mechanism .is rendered :e'fiectiveto stop the a description te machine at a predetern'iined point in the cycle of traversing moven'ient, by cam-operated lever interposed between parts which are attached to the control valve and the control level, respectively.

These and other features of the invention will best be understood from the following n in connection with the accoi'npanving erawings. in which Fig. i is a front el vation of the machine with a part'ot the-tran'ie broken away to show the internal construction;

The illustrated machine is an cage setting machine having provision for relativtraversing movement between a shoe and a re idly vibrating e lp e setting-tool. to tran in the point of application of the tool around the edge of the sole oi the shoe. In t he illustrated machine the traversing movement is effected chiefly by moving the work support on the frame of the machine the tool being so supported that its position may be adj usted to compensate for variations in the contour and plane of the edge of the sole. 7

The work support comprises a laterally disposed L -shaped frame or jack upon the lower arm of which'a toe rest 22 and a heel rest 24 are mounted. An adjustable clamp 26 is also provided to embrace the count 1' part of the shoe to position it in the jack and a toe clamp 28 is movedagainst the toe of the shoe by a hand-operated lever 30 to hold the work, the tension or this clamp being adjustable by means of a hand whee The jack and tool are moved relatively by automatic mechanism to transfer the point.

of operation of the tool around the sole edge. and mechanism controlled by feelers bearing uponthe sole edge and by feelers bearing upon thetread v.ce of the sole near its edge. imparts the relative angular movements between the shoe and tool that are necessary to insure thatthe acting face of the tool shall bear evenly upon every part of the sole edge uponwhich it operates. I

The ack 201's secured upon the upper end of a vertical spindle 42 journaled in bearings at one end of a frame ll of which the other end. is pivotally carried at 46 (see Fig. El upon a second frame 48 that swings about vertical spindle 50 supported in the machine frame. The two frames at and l8 in their mean position are disposed approximatelythe mean of a variety of contours of shoe soles; the relative traverse of the tool and sole edge being brought into exact agreement with the contour of the shoe under operation by the horizontal and vertical movements which imparted to the jack and tool re spectively by the feel r mechanism.

The mechanism for driving the jack 20 comprises a slide 56 (Figs. 2 and 3) that is mounted to reciprocate in guideways 58 and 60 attached to or formed upon the" machine frame. The slide 56 is coupled by a piston rod 62 to the piston 64 of a hydraulic cylinder 66 s cured the machine. Motion is transmitted from the slide 56 to the ack by means of two chains or other similar flexible members (38 and 70. The chain 68 is secured to the slide 56 at one end and after passing. around pulleys 72, 7e and 7G is attached at its other end at '78 to the far side of the cam 52. The chain 70 also secured to the slide, passes around pulleys 80, 82 (shown in Fig. 2 directly below the pulley Tet), 84., 86, 88 as shown in Figs. 2 and 3, and is fastened to the cam at 90. To increase the motion derived from the slide the pul eys 7 and 82 mounted one above the other upon the slice while the remaining pulleys except 8t are carried upon the machine frame. The pulley 8% is carried upon a lever 92 pivoted to the machine frame and is acted upon by a spring pressed rod 94 to keep the chains 68 and 70 under the necessary tension. I desired the chains instead of being attached to the cam 52 may be secured to a pulley of correspondins: formation.

By the connections above-described the j ack oscillated from side to side by the reciprocation of the do and the direction oi motion t ll the it w reversed automatically by the following mechanism: 2:. reversingcam 96 l) journaled in the machi e irame below the jack spindle 42 is flexibly .coupled to saidspindle by a universally-jointed connecting shaft 98. The reversing cam 96 partalres of the turning nioven'ients of the ack and a high part of the cam is adapted to engage and operate lever 100 pivoted on the n achine frame. The lever 100 by way of a .iustable connections presently be de ed actu ates the valve 102 (upper left side of Fig. 3) that controls the supply of lOU fluid to both sides of the piston 64 in the hydraulic cylinder 66 before mentioned. The point of operation of the tool is transferred along the sole edge of the shoe, from the shank on one side ofthe sole, around the toe portion, to the shank on the. other side of the sole; the d rection of motion of the ack being reversed vhen thetool reachesthe, shank.

To adapt the machine for operation upon shoes of different sizes and styles, the points at Which reversal takes place are made adjustable, and as shoes of different styles vary in the relative lengths of the sole edge on 100, said spindle being movable vertically in the machine frame andcoupled to one mem her 106 of a clutch of which the othernienr 4 1 her isformed upon the guide pulley 88 over which, as aforesaid, the ack actuating chain extends. A vertical rod bored to receive the upper end of the spindle 104 is coupled. to

the latter by meansof a pin and slot connec-g tion which causesthe rod and the spindle 104 to rotate in'company but permits the spindle to be moved endwise independently of the rod to actuate theclutch 106. A sleeve in 'fric tional engagement With the rod has slidingly keyed to it a hub from which two tappet arms extend. These arms are adapted to engage with one or the other oftwo stop plates Which are adjustably mounted in the frame of the machine. Connections are provided from the vertical'rod -Wl11Cl1 are arranged to rotate a,

horizontal shaft 108 (near center of Fig. 1

and upper center of Fig. 3) to which there is connected a crank 110 pivoted to one end of a connecting rod 112 the other .end. of Wine-his arranged to operate the reversing valve 102.- Tlie position of the stop plates with respect to the tappetarms may be adjusted by means of rock shafts provided with operating handles" 116 and 118 (Fig. 1) which are disposedon the front of the machine in a convenient positionfor the operator. v

During rotation of the jack 20 the reversing cam 96 rotated with the. jack until the high 1 pa rt of the cam engages the lever and raises the spindle 10st to force the clutch members 106 into engagement. A rod actuated from thi clutch now rotates with the pulley 88 untilv one of the tappet arms has come into engagement with one of the stop plates, afterwhicli continued rotation of'the sa d vertical rod is effective to move the rock shaft 108 which, through the crank arm and the connect. ing rod 112, operates the valve 102 of the cyl= inder to change the direction of flow of the fluid in the latter. The motion of the ack 18 now reversed. in direction untilthe reversing cam operates by the connections above d ef scribed to cause the other'of the two tappet arms toengage the corresponding stop plate and'thus restore to the jack its original: difl; erection of motion. The directioniof mot on of the ack is thus reversed at each end of ts;

stroke, the exact point of reversal. depending upon the position into which the stop plates have been adj us'ted,it bei ng noted that as each stop plate is adjustable independently of. its

companion each endof the stroke of-tliejacln may be varied independently.

As the tool'operates along the sole edge of the shoe, it is always maintained iii a positionf normal tothe contour at thepoint of its engagement by a coritectin'g mechanism,herein after described, which angles the jack in 'a horizontal plane. In order to maintain the tooland slioesinth is relationwhen that poi? tion ofthe sole marg n at the uncture 'ofthe.

shank and forepart is reached, the ack must be turned through a considerableangle. Ad.-

vantage istaken ofthis fact by makingthe highpart of the cam 96 of such extent that it actuates the lever lOO and initiates the opera tion of the'reversing mechanism during that. period in WlllGll thetoolis travers ng'the, contou -of the sole edge at the juncture' of t he. shank and forepart. While the anglethrough Which the jack-must be tin'ned, as.the tool traverses this portionof the sole edge, varies Widely in shoes 'of differentstyles, yet this angle is of considerable extent ii1,aiiy oi'dinary shoe, and by making the higlrpa rt'of, the cam of an extent-Which s the mean of that required for operation on a greatvariety of shapes of shoes, the machine may be constructed so that it will operate satisfactorily on practically any style of shoe. 'Itavill be clear that'in this manner the'point atwhich automatic[reversal of the traverse takes place 'is'detei'mined or controlled by theshoe con: tour; and it Willbe evident alsothat Wl11l6 the reversing mechanism has its action lnltlilted upon the arrival of the shoe and jack inlpiei determined relation, such action is completed thereafter When a definite linear traverse between the shoe margin and tool shall liave oc curred: the extent ofthistraversebeing pref determined by the adjustment o", the stops In operating upon shoes otthe samesiz'e and style it Will be understood that although total length of 't-ravelgof the. point. of

the operation of the toolis the saine for -a.right. shoe as for a left thepoints at which reversal otthe direction of motion of; the jackshould take place are different-for each shoe;

the configuration .of the sole edgeof the 7 right shoe difiering only from'that oi'f jthe" sole edge of the left shoe in that t s reversed laterally. i

In order that, as theinachine' has 915-.

Provision is made for effecting a relative shift 01" the tappetarmsand the stop plates so that either portion of the stop plate may be brought into'operative relation with a tappet arm. It for this purpose of ohtaining a ready adiustineut for ri hts and lefts umeew ta-p'pet arms are L ovideu and that the huh of the arms is sliding' y keyed upon the sleeve on the vertical 1 The two 'aortion's of each stop plat hei located at different levels each tagpet arm can be moved into operative relation with either ot' the said portions of the stop plate to which it appertains by the raising or lowe'ring of the hub; and this operation may he vedect-ed by means of an operatiu handle secured to a I-OClCSllilft u pen which an ezcenengages a groove in the hub;

opera-ting upon shoes that diiier some what Widely from the normal (for exan'iple shoes with pointed toes or shoes with square toes) it Will be evident that it the speedot the jack actuating mechanism is in: iitaiiied constant the edgesetting tool wil travel over different parts-of the sole edge with different velocities. In order to maintain constant the rateof relative travel of the tool in relation to the sole edge of such shoes, mechanism is provided for varying the speed oi the piston 64in the hydraulic cylinder This mechanisni comprises a long; conical valve 122 for regulating the speed of admission ()1 the fluid to the cylinder and this valve is also a to start and stop the trai 'e'rsiug movement The valve is connected by a ho izontal linl; 12 1, Figs 3 and 5, to an upright lever fixed upon a rockshatt 126 journ edin the machine frame, the rockshatt. having fixed upon it another 7 lever 128 Fia'. adaoted to engage a; sliding collar 130 (Fig. abutting against the cent a l portion ot a *er 132 that ispivoted r2 on a semi-tubule 134 rotate-bl}; mounted in the machine ti Qne'end' of the lever 132 rests a changing cam 136'to1ined the cant so as to rotate in un the jack 20 The contour ot the is such that, as the jackis moved to to the tool di'liereiit parts'ot the 01 the shoe the lever 132 is ac mm 15-36 an l move? the \u i-lv I and close the conical valve extents and thus to alter the p and hence the speedoi the acl speed at parts oi the sole et 5 e ment of the cha ns slide [-6, the speec to the 1acl: is me te d at; i tumor} 15 apparatus l and x ich varies the veloc- "ion of the entire driving mechabe clear that the eii'cct of is superposed upon or employed to inoc e that of the other.

A trio tion device is provided to maintain the frame 134 and the bush 140 iii the positions into which they are adjusted. that supports the frame 13% upon which the lever 132 is pivoted is' screwed at its end into the machine frame; and hv turning a The spindle 138 1 about the common axis of thesha-nk and the sleeve 156; while the sleeve 156, tool holder .150 and bearingfraine 158, during their lateral and vertical movements in tollow ng the sole edge, are maintainedhorizontal by the action of the twin links 164 and 166. These -links in conjunctionwith the bell crank 172 and link 176 constitute a parallel motion device supporting the bearingiiraine 158.

The edge setting tool 148 vibrated rapidly about the vertical ails of the piece 152 by connections from av shaft 178 which may be oscillated by anysuitable 1 echanism.

The tool 14:8 is pressedagainst the sole edge of the shoe by means of a spring 196': and by the co-operation o lf this spring with the cam- 52 on the lower end of the spindle 42 of the jack 2O the point of operation of the tool is caused'to travel along the sole edge during the movement of the jack. But

it is necessary dur ng the movement of the 7 jack that there be angular movement in a horizontal plane between the jack and the.

tool to maintain always the acting face of the tool in proper engagement with the sole edge at every part of the contour thereof. Further, it is necessary also that the jack and tool be turned relatively about an axis that isnorni'al to the acting face of the tool owing to the fact that all 'parts'ot. the sole do not lie in the same plane. These move-. ments of adjustment between the jack-and thetool are effected automatically by the correcting devices hereinafter described,

i The correcting device for angling the. jack in a horlzontalpla-ne in relation to the tool comprises a hydraulic cylinder 198 (Fig, 3), the piston rod of whichis connected by a link to a jack correcting lever 200 pivoted at 202 to the machine frame. This lever sup ports thetwo rollers 54-, hereinbefore referred to as engaging the groove Millie cam 52 on the lower end of the-jack spindle; A valve 204 1) of the hydraulic cylinder is of the rotary type and is controlled by twoedge feelers (not shown) which under the action of suitable springsbear upon the sole edge, one on each side oil the edge setting tool 1 18. These edge feeler are interconnected by means of a crossbar which is joined to the upper end oi a shaft 206the lower end of which is joined to the,valvel. hen the tool is hearing evenly upon the sole edge the valve 204 is maintained closed but when he feelers aremoved'relatively to one an-. other by changes in the contour of the sole edge passing the tool, its movement is eliec tive to cause a rotation ofthe shaft206 and hence o1 the valve 204. The valve being thus actuated causes the piston ot the cylinder 198 to be set in motion so that the jack correcting lever 2001's turned upon its pivot 202. The jack 20 being connected to the lever by the rollers 54, 54 and'the cam'52 will also be swung about the pivot 202 of the 'sole edge while the machine is in operation,

thrown automatically out or lever as a-center until the soleeedge of the shoe on thejack is returned by such move inent to the positionin which thetool, bears evenly uponfity by which time the edgefeelers 7 will, likewise'be restoredi'by the movement of the sole edge totheir' initial position and they willolose the valve, 204: and stop theme-, tion of the pistonandot the parts connected therewith. 7 j f l The correcting device that'efiectsi a relathe tool, comprises a hydraulic cylinder 210 I (Fig. 2) thepiston'ot whichis connected a thrust rod with an extension 2ltiron1,

.75 tive turning movementoi jack and tool' about an ELXIS that 15 normal to the acting face. of

a' collar that is secured to tl eprojection.154:

ironi'the sleeve 155. A spring "(not shown) .connects the sleeve-156 and the frame l58and opposes the thrust ofthe rod,

sole edge or to-re nove it therefrom; a startmg and stopping lever or controlling lever 230 is provided which is fixed'upona rockshaft 232 journaled in the. machine frame.

The rockshaft 232 has'upon it'an arm 234 inside the frame to which is pivotally linked a plunger 236. into which extends a rod 238 free to turn within a bearing upon the frame lever'168. The spring 196,;thedtnictionof which is to keep theto'ol pressed against the surrounds the rod 238 and; abut-sat its lower end against acollar supportedby projections from a; nut 242 working on a threaded portion ofthe rod 238 and at itsnpper end against an abutment 2441 pivoted on the lever i i0 168; A'collar 246 secured to the upper end of the rod 238 operates to limit'the inov'elnent of the rod in the abutment 241-4; under the influence of the spring 196, By this coiistructionthe tool can be moved yieldingly toward the sole edge and removed,positivelytherefrom. Preferably the plunge1f236 works in a dash pot 2+l8 which cushions the movement of thecontrolli'ng lever 23O and the tool supporting lever 168; when the machine is action.

A cam 250 (Fig. 5) onthe rochshaft232 s adapted to engage an arm extended from a lever 251 on the .rockshaft'l26 (FigsI 3an'd that is coupled to the conical valve ,122

sothat this valvelnay beyshut until the con-' j trolling lever 230 has been moved sufficiently to bring the toolvinto engagement with the work, at which time the valve Will be permitted to open by the disengagement of the cam 250 from the arm aforesaid to start the fhandle 262 pivoted to the free end of the'controllinglever 23.0 is provided with a tooth 26 i (-Fi adapted .to engage an aperture in the machine frame so as to hold the lever in the positionwhioh it occupies while the machine is running.

Then' achlne compr ses an automatic mechanism that stops its operation after a predetermined number of traverses of the tool aroundthe sole edge. And this number of traverses can be varied by an adjusting device. To thisend a tappet piece 2% (Figs. 1 and t) on the reciprocating rod 112 that forms'part of the melt-reversing valve-actw ating mechanism is adapted to lift one end of a lever 268 .pivoted upon the mac no frame. This opens a valve 270 (Fig. 1') which operates a plunger 272 operatively connected to an arm 2714 (Figs. 1 and 3) of a rocking frame 27 6 that turns upon a spindle .supported inthe machine frame. Another arm 2.7 8 (Fig.3) on the frame carries a pawl 267 that engages a ratchet wheel 280 that ha'scoupled to it an arm 282. This arm has acam face that is brought by rotation of the ratchet wheel 280 into engagement with a springpressed plunger 284i mounted in the machine frame. The plunger 28% when moved "endwisefby the cam face of the arm 282 forces the tooth 264 on the handle 262 out of the aperture in the machine frame thus releasingjthe controlling jlev er 230 and allowing the tool and its supporting device to fall away from the work. Inthe operation of this automatic mechanism the ratchet wheel 280 is'moved by the connections from the tappet piece 266 at each reversal of the jack until the latter'has made the number of movements for which the IIIQCllElDlSlD is set, when the cam arm 282 will release the controlling lever 230, and the tool will move away from the work. Means including a rotatablestuh shaft 290gare provided for adjustahly determining the number of traverses of the'jacl: past the tool. This release of the controlling lever 230 is not immediately effective (as later .describeiil) to stop the machine.

A pump 292 is provided which supplies fluid under the requisite pressure to the hydraulic cylinders of the machine and there is an air chamber 294 into which the fluid is pumped before passing to the hydraulic .cyl inders. Power is supplied to .the machine through a shaft 296 on which mounted a driving pulley 298 (Fig. V

Mechanism is provided which is arranged to interrupt the supply of power to the tool prior to the completion of the traversing movements. in this machine the stub shaft 290 which'is rotated to determine the number of traverses of the ack past the tool has fixed on it an arm 8012 (Figs. 1 and 3) which is connected by a bar 308 to ablock 30-t slidingiy mounted on asec-ond bar The position therefore of the block 30% on the bar is varied as the number of traverses is variet. The bar 305 is pivotally connected at to the starting and stopping or controlling lever 230. The bar 305has formed at its right-hand end a notch 308 which en the starting lever 230 is moved manna y coo. into the position shown in Fig; l to start the machine, engages a block 2309 carried .on one lever pivotally the starting lever is moved into position to start the machine the belt is tightened to drive the edge setting iron. At the end ofeach traverse of the shoe past the-tool the shaft 290 of the counting mechanisu'i is moved one step and therefore the block 30%, which is slidingly mounted on the 305 is moved step-by-step along the bar and at the end of the last traverse hit one is moved beneath screw 320 carried in one arm 321 of alever pivoted in the frame of the machine. The other arm of this lever has in it a. screw 39.3 which is positioned in the path of a cam carried on the slide 56 so that when the shoe reaches one end of its traverse and the shoe is at the reversing point in its last traverse the other arm 3521 of the lever is depressed carryingwith the screw 320 to engage the block 304: (Fig. 1) and move it and the righthand end of thesecond 305 downwardly against the action J L the edge setting iron. The ei-sed past the iron from one do to the other with the oscillations of the iron eliminated so that the sole edge is wiped round once by the non-vibrating iron to smooth off any waves which may he left by. the vibratin iron.

At the same vtin'ro that the belt is s'l itis also desirable to lift the belt out o" fact with the highest portion 0 I pulley'iBQi so as to prevent the iron ing driven by such contact after til". slackened and for this purpose the recon 328 of the lever 315. to which the beittig. ing 21111131? is fixed. is connected by a rear wardly[extending link to an arm 030 a belt raising men'iher 331 pivoted upon a'hor Zontal shaft -arried in the frame of the nrerclocliwise 'by the arm and the oscillating shaft is stopped machine. The belt raising member 331 is in the form of a fork (Fig. 6) straddling the upper portion of the driving pulley 327 and having the upper surfaces or" the fork arms 1 curvedto substantially the same radius as the "lhe belt 319 of such I radius of the pulle width that it projects over the edges otthe pulley'so that when the raising member 331 is swung upwardly as the beltis slackened itengages the belt at each side'ot the pul ey and lifts it clear of the pulley. A stop (notshown) is provided to limit the upward movement of the raising member 331 so as to prevent the belt from being drawn against the lower portion of the pulley.

When the edge setting iron is stopped it is desirable that it shall be in the mid position of its oscillation-and for this purpose theedgre setting iron oscillating shaft (Fig; which is arranged to oscillate the vertical shaft 178 (Fig. l) has fixerl on it an eccentric ecc ntric 334 and as the high part of the eccentric comes round it is irictionally engaged with the iron in its central position.

in machines of the kind referred it: has

been usual to ca-use theedge setting, iron to be moved away trom the shoe and to stop the ma chine at a position which is comparatively straight and which therefore renders easy the movement of the iron into engagement with the edge of the sole on the next shoe to be operatedupon. Thelast traverse ot' the shoe past the iron was therefore not a. complete traverse from one sideof the shoe to the other inasmuch as a portion. "from a. position alongthe 'forepart to the shank oirone-side, not op ated the edge of the sole .until the end of the.

upon.

during the last traverse when the iron is stationary and is acting to smooth or sleek the edge of the sole the iron were ren'io'ved be tore the end of the traverse an undesirable mark. such asa hump of wax, would be left on the edge of the sole at the point where the iron was removed. In the present construction, therefore. the iron is not removed from traverse at the shank is reached. in ma.-
